SLL error during requesting to axis camera

I want to make an http request to axis camera in order to change some parameters of camera automatically. I wrote a simple PyQT GUI and used it to run a simple code.

In this code, I use a post request to send the parameter I mentioned earlier and other authorization things to access the camera.

from PyQt5 import QtCore, QtGui, QtWidgets
import requests
from requests.auth import HTTPBasicAuth
from requests_toolbelt import user_agent

class Ui_CameraSetttings(object):
    def setupUi(self, CameraSetttings):
        CameraSetttings.setObjectName("CameraSetttings")
        CameraSetttings.resize(663, 508)
        font = QtGui.QFont()
        font.setFamily("Century Schoolbook L")
        CameraSetttings.setFont(font)
        self.Lname = QtWidgets.QLabel(CameraSetttings)
        self.Lname.setGeometry(QtCore.QRect(20, 20, 151, 17))
        self.Lname.setObjectName("Lname")
        self.LIP = QtWidgets.QLabel(CameraSetttings)
        self.LIP.setGeometry(QtCore.QRect(20, 70, 151, 17))

        self.CameraName = QtWidgets.QLineEdit(CameraSetttings)
        self.CameraName.setGeometry(QtCore.QRect(150, 20, 113, 25))
        self.CameraName.setText("")

        QtCore.QMetaObject.connectSlotsByName(CameraSetttings)

    def retranslateUi(self, CameraSetttings):
        _translate = QtCore.QCoreApplication.translate
        CameraSetttings.setWindowTitle(_translate("CameraSetttings", "Dialog"))
        self.Lname.setText(_translate("CameraSetttings", "Camera Name"))
        self.LIP.setText(_translate("CameraSetttings", "Camera IP"))
        self.LIR.setText(_translate("CameraSetttings", "Camera IR"))
        self.comboBox.setItemText(0, _translate("CameraSetttings", "auto"))

    app = QtWidgets.QApplication(sys.argv)

    ui = Ui_CameraSetttings()
    ui.setupUi(CameraSetttings)
    CameraSetttings.show()
    sys.exit(app.exec_())

But it gets an error about certificate verify failure as shown below. I tried many ways to send Certificate (PEM format) but none of them worked. Where is the problem?
